8 Claims.

rThis invention relates to new and useful improvements in covers forcontainers, jars, etc., and has particular reference to a constructionwhich permits the cover to be pressed closed tightly.

More specifically, the invention proposes a cover as mentioned which islcharacterized by a hollow body having a top wall portion continuinginto a skirt portion formed with threads for threadedly engaging uponthe neck of a container, jar or the like, and a novel construction ofrigid member, sealing element and screw for accomplishing the presstight arrangement previously referred to.

More specifically the invention proposes that the screw be threadedlyengaged through the top wall portion of the cover and abut against therigid member which in turn will press the sealing element upon the edgeof the neck of the con.- tainer for producing the tight arrangementpreviously described.

Still further it is proposed toprovide two sealing elements. Onearranged to be pressed against the edge of the neck of the container andthe other to be simultaneously pressed against the edge of the neck ofthe container andthe skirt portion of the cover body.

Still further the invention proposes the construction of a cover asmentioned which is simple and durable and which may be manufactured andsold at a reasonable cost.

' For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and tol the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a vertical sectional view of the press ight cover constructedaccording to this invention and shown mounted upon the neck of acontainer or jar.

Fig. 2 is an enlarged detailed view of the top portion of Fig. l.

Fig. 3 is an elevational View looking in the direction ofthe line 3-3 ofFig. 2.

Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 2.

The press tight cover for containers, jars and the like, according tothis invention, includes a hollow rcover body 2| having the topwall 2land a skirt 2 Ib. A sealing element 22 is mounted 55 within the coverbody and has a face portion 22a engaging the inner face of the skirtwall 2lb and another face wall 22h which engages the top edge of theneck 23 of the container or the like. An auxiliary sealing member 24extends through an opening in the sealing element 22 and also engagesthe edge of the n-eck 23.

A rigid element 25 has a beveled portion 25a which engages against acomplementary beveled portion 22c upon the sealing element 22. Thearrangement is such that when the rigid element 25 is forced outwardsbecause of the contacting beveled surfaces, the sealing element 22 willbe simultaneously urged against the inside face of the skirt portion 2ib and against the edge of the neck 23.

An arrangement is provided for lifting the rigid element 25 outwardswhen desired. This arrangement includes the screw 26 threadedly engagedthrough the top wall 2la and provided at its inner end with a flangeportion 21. This flange portion is rotatively connected with the rigidelement 25. The rotative connection is accomplished by the flange 2engaging into a recess formed in the rigid element 25 and rotativelyheld in this recess by an annular member 28 mounted upon the rigidelement 25 and partially extended over' the recess. The screw IB isprovided with a head 29 upon its outer end by which it may readily beturned.

An auxiliary rigid element 30 is superimposed on the auxiliary sealingelement 24 and is adapted to move outwards to press the auxiliarysealing element against the edge of the neck of the container 23. Morespecifically the auxiliary rigid member 30 is disposed within a recess3| formed in the bottom of the rigid element 25. These rigid elementsare loosely connected together by several pins 32 mounted upon. one ofthe elements and engaging in openings 33 `formed in the other of theelements. 'I'hese pins and grooves are arranged to permit slight axialmovement of the rigid elements relative to each other. The auxiliaryscrew 34 threadedly engages through the screw 26 and passes through anopening 35 in the rigid element 25 and abuts against the top of theauxiliary rigid element 30.

The top portion of the outside face of the skirt portion 2lb of thecover body 2| is provided with serrations facilitating the gripping ofthe body 2| when it is desired to engage and remove the body from theneck 23.

The operation of this form of the invention is as follows:

When the screws 29 and 34 are tightly screwed down the rigid elements 25and 30 will clamp the sealing elements 22 and 24 tightly against theneck 23. Furthermore the sealing element 22 will also be tightly clampedagainst the inner face of the skirt portion 2lb of the cover body. Thisserves to assist in. locking the cover body 2| against being unscrewed.Furthermore the neck 23 will be tightly sealed by the sealing elements.

To remove the cover it is necessary that the screws 26 and 34 beloosened. This releases the pressure upon the sealing elements 22 and24. Then the cover body 2| may be screwed off of the neck of thecontainer.

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to thepreoise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
